A compound that contains only carbon, hydrogen and oxygen has the following
2 answers:
Answer: A) C5H8O2
Explanation: Let's assume we have 100 grams of the unknown compound. We can then find grams for each element by multiply it's percentage times 100g. (e.g., carbon at 60% gives 60 grams of C). Then divide the mass of each element by it's molar mass. That will normalize the number of that element in relation to the others. E,g,, the 60 grams of carbon, divided by its molar mass of 12.01 g/mole gives 5 moles of C atoms. For H we get 8, and for O we get 2. That gives us the empirical formula C5H8O2

Neutron activation is the process in which atomic nucleus capture free neutron or neutrons.
Cobalt-60 is produced in nuclear reactors in process of neutron activation from parent isotope cobalt-59 (see the picture below).
Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.
Cobalt-59 and cobalt-60 are the isotopes of chemical element cobalt.
Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).
